Add a luxi call for multi-job submit

As a workaround for the job submit timeouts that we have, this patch
adds a new luxi call for multi-job submit; the advantage is that all the
jobs are added in the queue and only after the workers can start
processing them.

This is definitely faster than per-job submit, where the submission of
new jobs competes with the workers processing jobs.

On a pure no-op OpDelay opcode (not on master, not on nodes), we have:
- 100 jobs:
- individual: submit time ~21s, processing time ~21s
- multiple: submit time 7-9s, processing time ~22s
- 250 jobs:
- individual: submit time ~56s, processing time ~57s
run 2: ~54s ~55s
- multiple: submit time ~20s, processing time ~51s
run 2: ~17s ~52s

which shows that we indeed gain on the client side, and maybe even on
the total processing time for a high number of jobs. For just 10 or so I
expect the difference to be just noise.

This will probably require increasing the timeout a little when
submitting too many jobs - 250 jobs at ~20 seconds is close to the
current rw timeout of 60s.
